Gameplay ideas

Dear Mojang,                                                                                                                                               

Have a few ideas for a new feature for Minecraft.

 It would be awesome if when you splashed a zombie with a potion it would turn into a skeleton. It would be then defending you like a dog. My next idea is being able to throw the spear. Finally, you can also add giants, they can be 5 blocks tall, and they will have 25 hearts, and they would spawn in the swamp. 
                                                                                                                                                                      Thank you for Minecraft I play it every day, and it is one of the best videogames in my opinion. I have been playing for a couple of years.  
                                                     

Sincerely,
